ASC OS-125MF MEMS Capacitive Accelerometer
Analog voltage output acceleration sensor for the demanding requirements of offshore applications
About the ASC OS-125MF
ASC’s Offshore (OS) series capacitive accelerometers are based on capacitive sensing technology and produce an analog voltage output proportional to the input acceleration.The accelerometers can measure both static (gravity) and dynamic accelerations. ASC’s OS series can be used for very low to medium frequency vibration measurements. The OS series features a MEMS sensor element where the seismic mass is connected between two conductive capacitor plates. When subjected to an input acceleration, the seismic mass oscillates between the two
capacitor plates and there is a change in the capacitance. This change in capacitance is converted via an ASIC (Application Specific Integrated Circuit) into a low impedance analog voltage output signal.
ASC’s uniaxial capacitive accelerometers ASC OS-125MF are analog voltage output sensors and have been developed for the demanding requirements of offshore applications.The robust housing and the connection cables are suitable for immersion in salt water and are designed to work at 1m water depth. The sensors can be powered by a DC power supply (+5V to +40V) where the output voltage is independent of the supply. They operate in a differential configuration, which results in an improved S/N ratio due to common-mode external noise rejection. ASC OS-125MF operate in a wide temperature range either from -15°C to +70°C (standard) or even -55°C to +125°C. The sensors exhibit exceptional temperature stability, very low non-linearity and can withstand shocks as high as 6000gpk. The hermetically sealed ASC OS-125MF sensors feature a robust and corrosion proof stainless steel housing. A very high flexible and rugged cable provides a simple mounting. The sensors are supplied with 1 meter detachable cable as standard.
